  2. Active Scan method used for discovery When a beacon or discoverybeacon is received, performsector sweep (RTXSS). Discovery beacon must have A-BFT. Need to make sure both STAreceives DBandCapabilityelement, even if both STA have not received a beacon. This is necessaryfor PCP selection. Need to define where thediscovery loop ends.

  3. Proposed changes to D3.0 10.1.3.2b DBand Beacon generation before network initialization <editor note: change P323L31 as indicated> A DBand STA can transmit DBand Beacon frames before network initialization to discover and, possibly, perform beamforming(e.g., during the A-BFT) with another DBand STA… <editor note: insert at the end of the paragraph at P323L37> In addition, the STA shall set the A-BFT Length field to a value greater than 0 and the Next A-BFT field to a value equal to 0. <editor note: insert paragraph at P324L1> A DBand STA that is transmitting DBand Beacon frames with the discovery mode field equal to one shall cease transmitting these beacons when it has received a DBand Beacon frame from another STA, or when it has received acknowledgement of a transmitted Probe Response frame. If a network is not initialized, the DBand STA can resume transmitting DBand Beacon frames with the discovery mode field equal to one.

  4. Proposed changes to D3.0, cont. • 10.1.4.1 General • <editor note: insert paragraph at P329L1> • In the DBand, the Active Scan procedure (10.1.4.3) can be used for device discovery prior to initializing or joining a network. • 10.1.4.3.3 Active scanning procedure • <editor note: change P330L6-10 as indicated> • e) Perform the Basic Access procedure as defined in 9.3.4.2 within a CBAPif the STA operates in the DBand; • f) Send a probe request to the broadcast destination address or, in the case of theDBand only, upon reception of an ScS Feedback frame send a probe requestto the MAC address of the peer STA identified in step (d), with the SSID and BSSID from the MLME-SCAN.request primitive. When transmitted in the DBand, the transmitted probe request frame contains at least the DBand Capabilities element. When the SSID List…
